Hacking with Modules
There are many modules available that provide a great shortcut when hacking together a project. These modules are usually a tiny PCB with a few components on them and some convenient connection points. They make it very easy to use some surface-mounted ICs that would otherwise be very difficult to solder connections to. Many of these modules are designed to be used with microcontrollers like the Arduino.
In this chapter, you will explore some of the more fun and useful modules available from suppliers like SparkFun and Adafruit, most of whose modules are also open-source hardware. So you’ll get to see the schematics for them and even make your own modules using the design if you wish.
